EAST HAVEN — A security specialist who filmed himself entering his daughter's middle school to illustrate potential gaps in security in the wake of a December school shooting rampage in the state has been arrested.

Angelo Appi Jr. turned himself in to police Tuesday and was charged with breach of peace after taking video at Joseph Melillo Middle School in East Haven in the past month.

Appi, of East Haven, posted a video on Facebook showing that the front door was open when he arrived to pick up his daughter after school hours. Concealing his cellphone in a coffee cup, he filmed himself entering the school and moving around inside unchallenged.

"The only comment that I made was be happy that I came in there with a cellphone, that I'm trying to expose the security flaws," he told WVIT-TV. "I walked in the school and nobody asked me what I was doing there, how I got into the school and who you are."

The school superintendent said the volleyball team propped the door open as players moved equipment.

As he defended his actions, Appi alluded to the Sandy Hook Elementary School shootings last December in Newtown, about 25 miles from his daughter's school, that left 20 first-graders and six educators dead.

"It could have been somebody else in that school besides me," he said. "And we don't want to relive that again."
